Electronic spin lattice relaxation in oligoarylenes in the naphthalene-benzene copolymer
Spin-lattice relaxation of paramagnetic centres in the naphthalene-benzene copolymer and in the products of its pyrolysis has been investigated in some detail at various temperatures. It appears from the experimental results that two-step Orbach-Aminov type relaxation processes take place in the pyrolyzed samples, and may be accounted for satisfactorily through the relaxation model in terms of exchange-bound clusters. The results of the relaxation measurements are compared with the data obtained by infrared, and by elemental analysis and X-ray studies. © 1986
Paramagnetism and electron spin-lattice relaxation in thermolyzed polyphenylacetylene
The EPR spectrum of thermolyzed polyphenylacetylene (PPA) is analysed. In the case of low power levels the shape of the EPR spectrum is attributed to the presence of paramagnetic centres localized on structurally different segments of the PPA molecule. Experiments showed the linear dependence of the electron spin-lattice relaxation time T1 in the temperature range 3-66°K. The experimental values of T1 are of the same order of magnitude as the calculated values. © 1974
The electron spin-lattice relaxation in pyrolyzed poly-2-methyl-5-ethinylpyridine
The temperature and field dependences of the rate of electron spin-lattice relaxation (ESLR) have been studied on poly-2-methyl-5-ethinyl pyridine (PMEP), which had been pyrolyzed at various temperatures. The experimental results are interpreted from the aspect of the theoretical calculations predicting the diversity of these dependences in the case of linear-and laminar-structure polymers. The results of the evaluations are compared with those of elemental analysis and IR-spectroscopy. © 1982
Newly identified climatically and environmentally significant high-latitude dust sources
Dust particles from high latitudes have a potentially large local, regional, and global significance to climate and the environment as short-lived climate forcers, air pollutants, and nutrient sources. Identifying the locations of local dust sources and their emission, transport, and deposition processes is important for understanding the multiple impacts of high-latitude dust (HLD) on the Earth's systems. Here, we identify, describe, and quantify the source intensity (SI) values, which show the potential of soil surfaces for dust emission scaled to values 0 to 1 concerning globally best productive sources, using the Global Sand and Dust Storms Source Base Map (G-SDS-SBM). This includes 64 HLD sources in our collection for the northern (Alaska, Canada, Denmark, Greenland, Iceland, Svalbard, Sweden, and Russia) and southern (Antarctica and Patagonia) high latitudes. Activity from most of these HLD sources shows seasonal character. It is estimated that high-latitude land areas with higher (SI ≥0.5), very high (SI ≥0.7), and the highest potential (SI ≥0.9) for dust emission cover >1 670 000 km2, >560 000 km2, and >240 000 km2, respectively. In the Arctic HLD region (≥60∘ N), land area with SI ≥0.5 is 5.5 % (1 035 059 km2), area with SI ≥0.7 is 2.3 % (440 804 km2), and area with SI ≥0.9 is 1.1 % (208 701 km2). Minimum SI values in the northern HLD region are about 3 orders of magnitude smaller, indicating that the dust sources of this region greatly depend on weather conditions. Our spatial dust source distribution analysis modeling results showed evidence supporting a northern HLD belt, defined as the area north of 50∘ N, with a “transitional HLD-source area” extending at latitudes 50–58∘ N in Eurasia and 50–55∘ N in Canada and a “cold HLD-source area” including areas north of 60∘ N in Eurasia and north of 58∘ N in Canada, with currently “no dust source” area between the HLD and low-latitude dust (LLD) dust belt, except for British Columbia. Using the global atmospheric transport model SILAM, we estimated that 1.0 % of the global dust emission originated from the high-latitude regions. About 57 % of the dust deposition in snow- and ice-covered Arctic regions was from HLD sources. In the southern HLD region, soil surface conditions are favorable for dust emission during the whole year. Climate change can cause a decrease in the duration of snow cover, retreat of glaciers, and an increase in drought, heatwave intensity, and frequency, leading to the increasing frequency of topsoil conditions favorable for dust emission, which increases the probability of dust storms. Our study provides a step forward to improve the representation of HLD in models and to monitor, quantify, and assess the environmental and climate significance of HLD
